Step-by-step explanation:
<u>Given:</u>
- Lemons - l and apples - a
- a = 35¢, l = 15¢
- Number of apples and lemons = 17
- Cost of lemons and apples = $3.95 = 395¢
<u>System as per question:</u>
- a + l = 17
- 35a + 15l = 395
Or
- a + l = 17
- 0.35a + 0.15l = 3.95
Step-by-step explanation:
Let the number of apples be a and lemons be l . Then ,
=> a + l = 17
Also ,
=> 35a + 15l = $ 3.95

Answer:

Step-by-step explanation:
Since the both have the same base 12 you can write like thus
X^2+5x-4=2x+6
X^2+5x-4-2x-6=0
X^2+3x-10=0
(X-2)(X+5)
X-2=0. X+5=0
X=2. And X=-5
